[0002]

2. Description of the Related Art Surveillance cameras are used in stores such as convenience stores to prevent shoplifting, or in banks to check suspicious users. As shown in FIG. 5, the surveillance camera 101 includes a lens unit 102, a camera housing 103 to which the lens unit 102 is attached, and a camera stand 104 attached to the camera housing 103. Then, using the camera stand 104, the camera support surface 201 such as a ceiling or a wall surface.
It is designed to be used by being attached to.

The lens unit 102 is connected to the camera housing 103 by an auto iris cable 105, and iris adjustment and the like are performed by an iris adjusting device incorporated therein. The above camera housing 1
A connector connecting portion 106 is provided on the side surface or the back surface of 03, and the connector 107 of the auto iris cable 105 is connected to the connector connecting portion 106.

[0004]

By the way, in the conventional surveillance camera, since the connector connection portion 106 is provided on the side surface or the back surface of the camera housing 103 as described above, the auto iris is seen when the surveillance camera 101 is looked up. Since the cable 105 is visible, the appearance is not only bad, but also the presence of the surveillance camera 101 is conspicuous.

The present invention solves the above-mentioned conventional problems by making the auto iris cable invisible when looking up at the surveillance camera.

[0006]

According to the surveillance camera of the present invention, a connector connecting portion for connecting an auto iris cable pulled out from a lens portion is arranged on an upper portion of a camera housing, so that the auto iris pulled out from the lens portion is arranged. The cable was routed along the upper part of the camera housing and connected to the connector connection part. Also,
By covering the connector connecting portion to which the above auto iris cable is connected with the cover, dust and the like are prevented from adhering to and accumulating on the connector connecting portion.
